IPC: G06F13/00
Filed: 1973-11-30
Abstract: 1441130 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 30 Nov 1973 [29 Dec 1972] 55564/73 Heading G4H A data processing system comprises: a plurality of subsystems; a control transfer interface unit; a data transfer interface unit logically independent of said control transfer interface unit; means connecting said subsystems to said control transfer interface unit in a multi-dropped closed loop; means connecting said subsystems to said data transfer interface unit point-to-point; a polling mechanism in each subsystem and associated with said control transfer interface unit for allocating temporary control of said control transfer interface unit to a subsystem desiring to initiate data transfer using said data transfer interface unit. As disclosed, the two interface units mentioned are associated with a programme-controlled CPU having main storage to/from which the data transfer referred to occurs. The closed loop involves a select in/out line which is raised by that station (viz that one of the subsystems or the control transfer interface unit) which has control when it wishes to offer control to the subsequent stations in the loop. Any station not requiring control passes the raised state on. The (first) station requiring control blocks the raised state and signals acceptance of control back using a deselect line. A station can request control from the station currently having it. Control can be passed even during a data transfer sequence as a consequence of the logical independence of the two interfaces.

Title: Quick Service Device on Automatic Compressed-Air Brakes
IPC: B60T15/30
Filed: 1966-12-22
Abstract: 1,174,059. Fluid-pressure brakes. OERLIKON-BUHRLE HOLDING A.G. 22 Dec., 1966 [24 Dec., 1965], No. 57513/66. Heading F2F. In a quick-service device on automatic compressed-air brakes, particularly for railway vehicles, a vent valve 30 comprises a valve body 32 to which is secured a piston 34 and an actuating member 1, acting through a disengageable intermediate member in the form of a two-armed lever 10, is adapted to open the vent valve 30 to connect a first chamber 38 connected to the train pipe 6a through the vent valve 30 and vented to atmosphere through a choke bore 40, a second chamber 37 mounted in the interior of the first chamber 38 being separated from the second chamber by the piston 34 such that when compressed air is in the first chamber 38, the piston 34 opens the vent valve 30 while compressed air in the second chamber 37 acts on the piston to close the vent valve. In the diagram, the apparatus is shown in the brake release position wherein air in the control reservoir 7a equals pressure in the train pipe 6a and a lower piston 2 is in its bottom position wherein the two-armed lever 10 is in the position shown under the influence of the spring 11 such that the lefthand prong 13 is just out of contact with a guide rod 14 and the vent valve 30 is closed under the action of the spring 41 so that the two chambers 37 and 38 are vented to atmosphere. An interrupter piston 16 is urged by the other prong 15 of the fork to the right as shown in the figure such that atmospheric air pressure prevails in the chambers 22, 24 and 27. When braking occurs, the pressure in the train pipe 6a is reduced and consequently the air pressure in the chamber 6 above the piston 2 of the actuating member 1 is lower than the air pressure in the chamber 5 so that the piston 2 rises to urge the prong 13 against the guide rod 14 and lift the vent valve 30 off its seat. Air from the train pipe then flows out of the chamber 6 into the chamber 38 of the quick service chamber 29 and escapes through the choke 40 to atmosphere. Air pressure also holds the valve 30 open by acting on the diaphragm 35 and also passes through the passage 28 into the chamber 27 to actuate the diaphragm 19 and cause displacement of the piston 16 towards the left so that the prong 13 comes out of engagement with the guide rod 14. This action initiates pressure in the brake cylinder 26 to apply the brakes. And the piston 16 remains in the left-hand end position until the brakes are released. The brake cylinder 26 is in communication with a control valve (not shown) through a pipe 25a.

Abstract: 1,241,855. Telescopic instruments. D. P. BUSHNELL. Dec. 5, 1968 [Jan. 2, 1968], No. 57728/68. Heading G2J. In a telescopic instrument such as a pair of binoculars Fig. 1 (not shown) one of the ocular lens housings 39 is coupled to a focusing ring 29 such that it is moved through its full focusing range by rotation of the ring through not more than 120 degrees. The ring is seated over a flange 26 on the objective lens housing (20) Fig. 1, (not shown), which contains prisms, or mirrors (17) and (18), and is secured by setscrews 30 which bear against a plastics ring 28 in a groove 27 of flange 26. The ring 29 has a tubular extension 31 having a cam slot which co-operates with a screw 34 in the collar 36 of a bridge member which is coupled to the ocular housing, and has a flange 37 into which the housing 39 is screwed. Rotation of the ring 29 by a knob 33 causes axial displacement of the bridge, and hence both ocular housings, relative to the objective housings (20). Each eye-piece has an individual focusing ring 41, and the interpupillary spacing is adjusted by means of a hinged bracket (13) on which the bridge member is mounted. In another embodiment Fig. 6 (not shown) a cam recess (76) is formed in the ocular housing (65), and a focusing ring (71) is mounted about a flange (58) on abridge member (56). A setscrew (73) is threaded through the ring (71) to extend through a slot (62) in the bridge member and engage a recess (74) in the ocular housing; a second screw (75) is threaded through the flange (58) to engage the cam slot. To provide centre focusing a wheel (86) Figs. 9 and 10 (not shown), is coupled by a flexible belt (88) to a focusing ring (83) on each ocular housing, or by a central toothed wheel (91) Fig. 11 (not shown) meeting with toothed focusing rings (92). In a further embodiment the objective lenses are moved for focusing instead of the ocular lenses, in a similar manner thereto. A locking device 100, having an actuating knob 101 pivotally connected by pin 103 in a recess 102 in a focusing ring 29A may be employed. A lock shaft 105, pivotally secured to knob 101 by a pin 106, extends through an opening 108 in the ring 29A and is pressed against a plastics ring 28 by a spring 109 acting on a flange 107 on the shaft. Depression of the knob 101 acts against the action of spring 109 to release the locking shaft. In another form of lock means (115) Fig. 14 (not shown), a threaded locking shaft (119) which abuts the plastics ring 28 may be operated by rotating a knurled wheel (118) on the shaft which extends through a slot (117) in the focusing ring.
